COTTON FIBER GLAND PACKING
Cotton Fiber Gland Packing is a traditional braided sealing material manufactured from natural cotton fibers and engineered for light to medium-duty sealing applications. To improve operational performance, cotton fibers are commonly impregnated with graphite, PTFE, lubricants, grease, mineral oil, or special sealing compounds.
This type of compression packing offers good flexibility, low shaft wear, and stable sealing performance under moderate temperature and pressure conditions. Cotton Fiber Gland Packing is widely used in water systems, pumps, valves, marine equipment, and general industrial machinery where chemical exposure and temperature are not severe.
